If rock is exposed to enough heat after metamorphism it will eventually
crystallize into magma.
solidify into magma.
weather into magma.
melt into magma.
melt into magma.
The Earth's orbit around the Sun is almost circular. Therefore, Earth receives
about the same amount of year-round
heat and light.
light and precipitation.

How would we use isotopic ages to infer the ages of the upper and lower unit in
this diagram?
The lower unit would be younger than an age on the crosscutting dike.
, The dike is younger than the lower unit but older than the upper unit.
An age on the dike would not help us because it is an igneous rock.
The upper unit would be older than an age determined on pebbles of the dike in
that unit.
The dike is younger than the lower unit but older than the upper unit.

location 5, on a relatively deep seafloor
location 4, along a beach
location 3, in sand dunes
location 5, on a relatively deep seafloor

there are no planes along which the mineral can break.
of the arrangement of atoms in the crystal lattice.
cubes are the most common way two tetrahedron can join.
halite is soluble in water.
of the arrangement of atoms in the crystal lattice.
Which of the following is a common use of a mineral?
